Eerie 13th Birthday Coincidence

understandinguncertainty.org was produced by the Winton programme for the public understanding of risk based in the Statistical Laboratory in the University of Cambridge. The aim was to help improve the way that uncertainty and risk are discussed in society, and show how probability and statistics can be both useful and entertaining.

Many of the animations were produced using Flash and will no longer work.

Soo I have a some what curious and eerie coincidence with my family. In particular with my immediate relatives. My fathers birthday is Feb 13th('68), my mothers is Apr 13th('65), mine is Dec 13th('89) and lastly my brother who is May 31st('99). So all very similar, but then my brother is the backwards one. What are the odds? *Years not really relevant per say, but are there for perspective. Also, if there's any astrological significance it would be entertaining. ~andrew.pease89@gmail.com
